While Microsoft has been touting that the Xbox Series X is the “world’s most powerful console,” the PS5 is outperforming it in early game tests, and Microsoft is working on why.As reported by The Verge, Digital Foundry has been analyzing some of the new games across both the PS5 – which is capable of 10.28 teraflops of GPU performance – and Xbox Series X – which is capable of 12 teraflops – and it’s not as one-sided as it initially appeared.

In Devil May Cry 5, the Xbox Series X has better performance in 4K and ray tracing modes, but the higher frame rate option runs better on PS5, with the frame rate gaps being more than 40fps in some cases.

“The dips look really strange to me, and it kind of suggests to me some kind of API limitation on the Xbox side where the GPU is being held back by something,” suggests Digital Foundry editor Richard Leadbetter.

Assassin’s Creed Valhalla, which has been heavily promoted by Microsoft, also runs a bit smoother on PS5, with the Xbox Series X version showing screen tearing and regular frame rate dips below 60fps.

The same story plays out in Dirt 5, where image quality and resolution go in PS5’s favor. Dirt’s developer Codemasters has acknowledged this peformance gap, and has already said it has a fix in the works.
